CALIBRATION SOFTWARE

When acquiring images from the detector, calibration is essential to obtain images of high quality. enables you to create and check the necessary values for the calibration.
NOTE

•  It is recommended to perform a calibration once per month for the following three months after the purchase, and then once every six month to ensure the quality of images.
• It is also recommended to turn on the detector for 15 minutes before the Calibration.
• The default values set in can be changed depending on the actual conditions of use.
  Security
  Calibration Software can not be used independently without being connected to the detector. The software cannot perform all actions, including moving to another menu and confirming settings, without the actual connection.

• Set additional Bad Pixel in [Pixel View]
  – Double click a pixel in the [Pixel View] to set the pixel as a Bad Pixel. Double-click the same pixel specified as a Bad Pixel again to cancel the selection.
  – If a pixel is set as a Bad Pixel, the value will be updated in the [BPM Analysis]. The specified Bad Pixel will be replaced with the calibrated pixel value.
• Save the final [User BPM].
  – When entering into another menu, the result file will be saved.
  – A pop-up message appears asking to select whether to save the file when leaving the current menu and entering into another one.
  – When saved, one [History] is added and the [BPM.raw] file is updated and saved.

Specify Additional Bad Lines in Pixel View

• This feature is to specify Bad Pixel not by pixel but by line.
• Select the check boxes for vertical or horizontal direction and double-click the pixel in [Pixel View] to specify a line in the selected direction.
  – For example, specify a line between 1522 and 2600, enter a value, and then select [Apply] to specify the line as a Bad Line.
